Thanks for contacting us.
This can be done for people logging into the CMS, but not for users on the public side. Once the poll is taken off-line, which means that it is removed from the page, then no one can see it on the public side. Keep in mind that removing the poll from a page does not remove it from the CMS. Users can still go to Modules > Polls
and select the poll and then the view button to see the results.
Feel free to contact us if you need further assistance.
All the best,
